   Keywords : Cardiovascular Magnetic Resonance Imaging CMR ; k-Space Filter; Sector Wise Golden-angle SWIG ; Kardiovaskulär Magnetisk Resonans Tomografi CMR ; k-rumsfilter; Sektorsvis Gyllene Vinkel SWIG ;

   Abstract : The aim of this thesis is to design and evaluate k-space weighting filters for simultaneously improving the spatial and temporal resolution of cardiovascular MRI, with the ultimate goal of improving the accuracy of quantitative flow measurements, which are important for diagnosis and follow-up of heart dysfunction. Two different k-space filters were implemented and evaluated retrospectively to already acquired data. READ MORE

3. 2. Development of an MRI-compatible Multi-compartment Phantom for Dynamic Studies

   University essay from KTH/Medicinteknik och hälsosystem

   Author : Jonas Ström Seez; Frederick Holmer Fann; [2020]
   Keywords : Dynamic studies; Dynamic phantom; Multi-compartment analysis; MRI compatible; PET; SPECT; Gamma camera; Nuclear medicine; Dynamiska studier; Dynamisk fantom; Multi-kammar analys; MRI kompatibel; PET; SPECT; Gammakamera; Nuklearmedicin;

   Abstract : Medical imaging based on radioactive tracers exposes the patient to radiation. For this reason, a phantom is preferably used for non-clinical studies such as routine quality assurance and research. The aim of this project was to design, build and test a multi-compartment phantom to be used in dynamic SPECT/CT, PET/CT and PET/MRI studies. READ MORE
